sets immediately upon contact with a for-- eign object it cannot be scraped or its thickness regulated after application to the paper at the tanks 5. It will be obvious that the first layer applied is not provided with any adhesive.

In order to secure the maximum strength in the Wall of the tube, the layers are arranged, when six strips of paper are used, as indicated diagrammatically in Fig. 2, so that no two joints are in line. It will be understood that no matter how many strips or layers are employed all joints are out of line.

a six ply tube is desired are numbered 1 to As illustrated in Fig. 2, the layers Where 6 inclusive. The joint or meeting edges of the first layer is spanned by layer number 2 the joint of No. 1 coming in the center of No. 2. The joint of number 3 is brought 4. The manner of so feeding the strips of paper to the mandrel is effected by adjustmg the relative positions of the strips as applied to the ,mahdrel as will be readily understood by those skilled in theart. What I claim as my invention is 1. The process of manufacturing paper tubing consisting in continuously feeding a plurality of paper strips spirally on to a mandrel and s reading an adhesive containing silicate o soda over a surface of said strips to adhere them together While at the same time maintaining the silicated surface untouched between the application of the silicate and its engagement with another strip.

strips untouched between the application thereon and the engagement with the other strips. 1
